✦ Synopsis

The mass spectral fragmentations of multiflorine, 13a-hydroxymultiflorine, 5dehydromultiflorine, 5-dehydro-13ahydroxymultiflorine, 5dehydro-11,12-secomultiflorine and 11,12-seco-12didehydromultiflorine were investigated. Fragmentation pathways, the elucidation of which was assisted by accurate mass measurements and metastable transitions, are proposed. These results create a reliable basis for distinguishing the above-mentioned from isomeric (previously reported) quinolizidine alkaloids.

gated compounds have two elemental compositions (Table ).

Conditions are reported for the reverse-phase HPLC analysis of gossypol and of someof its derivatives, including anhydrogossypol, gossypolone, gossypol hexaacetate, and Schiff's base derivatives. It is shown that field desorption (FD) and chemical ionization (Cl) mass spectrometry have advantages ov

Tetrodotoxin (TTX), a powerful sodium channel blocker, usually exists as a mixture of its analogs (TTXs) in natural sources. Due to the structural variation, some analogs are difficult to detect using the postcolumn liquid chromatography-fluorescent detection (LC-FLD) system. Liquid chromatography/e
